Question

Water vapor in the earth's air is an example of a solution. What type of solution would this be?
(Points : 3)
gas in a gas

gas in a liquid

liquid in a liquid

liquid in a gas

I put liquids in a gas for this one

Answer 1

@rishavraj

Answer 2

hmmm gas in gas

Answer 3

but water vapor is liquid gas ?

Answer 4

water vapour is aerosol....i think .......not sure

Answer 5

hmm okay

Becuase when you talk water vapor your hand gets wet

Answer 6

This is an example of a gas in a gas.

Water vapour is a gas. The reason your hand might get wet if you sweep it through water vapour is because the vapour CONDENSES onto your hand (i.e. changes phase from a gas to a liquid) as a result of heat transfer from the water vapour to your hand.

This condensation will only occur if under specific pressure/temperature conditions. Wave your hand in the air now and it won't get wet, even though there's plenty of water vapour around. But, wave your hand over a boiling pot of water and that's a different story.

Answer 7

it is just so tiny that we cannot see it and unable to distinguish with other gasses in the atmosphere. therefore, it falls into the definition of solution as defined in chemistry.
remember that water has the capacity to maintain three physical properties - solid, liquid and gas. Now the gas portion as a vapor is by no means an actual gas, it is just because of its physical size that we are not able to distinguish it from other real gas like oxygen, nitrogen and other gases you can list from table of elements; contrary to conventional knowledge that vapor is gas is something I would say only correct to certain extent and would propose that two molecules of water or a molecule of water is not gas, but liquid. It is the aggregate amount that is able to give us a visible distinction as liquid.

Water vapour is the gaseous form of water, just as ice is the solid form of water. It is as much a gas in air as the oxygen or nitrogen in air is. Gathering together more water vapour from the air won't give you liquid water any more than gathering together more nitrogen from the air will give you liquid nitrogen. What determines the state of the substance is not how much of it you have, but rather the pressure and temperature at which you have it, particularly with volatile substances like water.

The solid, liquid, and gas phases of water are all composed of the same water molecules, whether you have 1, 2, or 100 of them. This is why they're differentiated as phases (states) rather than entirely separate compounds. The same can be said of any other of the conventional gases found in air.

I don't mean to be pedantic, @nincompoop, but I also don't want misinformation to be spread. I might agree with some of what you said if you were referring to things like clouds or mist, which ARE composed of liquid water (albeit in the form of very small droplets), but the water vapour present in "air" is really a gas!
